300 /* About the relocation formatting table...
302 There are 256 entries in the table, one for each possible
303 relocation opcode available in SOM. We index the table by
304 the relocation opcode. The names and operations are those
305 defined by a.out_800 (4).
307 Right now this table is only used to count and perform minimal
308 processing on relocation streams so that they can be internalized
309 into BFD and symbolically printed by utilities. To make actual use
310 of them would be much more difficult, BFD's concept of relocations
311 is far too simple to handle SOM relocations. The basic assumption
312 that a relocation can be completely processed independent of other
313 relocations before an object file is written is invalid for SOM.
315 The SOM relocations are meant to be processed as a stream, they
316 specify copying of data from the input section to the output section
317 while possibly modifying the data in some manner. They also can
318 specify that a variable number of zeros or uninitialized data be
319 inserted on in the output segment at the current offset. Some
320 relocations specify that some previous relocation be re-applied at
321 the current location in the input/output sections. And finally a number
322 of relocations have effects on other sections (R_ENTRY, R_EXIT,
323 R_UNWIND_AUX and a variety of others). There isn't even enough room
324 in the BFD relocation data structure to store enough information to
325 perform all the relocations.
327 Each entry in the table has three fields.
329 The first entry is an index into this "class" of relocations. This
330 index can then be used as a variable within the relocation itself.
332 The second field is a format string which actually controls processing
333 of the relocation. It uses a simple postfix machine to do calculations
334 based on variables/constants found in the string and the relocation
337 The third field specifys whether or not this relocation may use
338 a constant (V) from the previous R_DATA_OVERRIDE rather than a constant
339 stored in the instruction.
343 L = input space byte count
344 D = index into class of relocations
345 M = output space byte count
346 N = statement number (unused?)
348 R = parameter relocation bits
350 T = first 32 bits of stack unwind information
351 U = second 32 bits of stack unwind information
352 V = a literal constant (usually used in the next relocation)
353 P = a previous relocation
355 Lower case letters (starting with 'b') refer to following
356 bytes in the relocation stream. 'b' is the next 1 byte,
357 c is the next 2 bytes, d is the next 3 bytes, etc...
358 This is the variable part of the relocation entries that
359 makes our life a living hell.
361 numerical constants are also used in the format string. Note
362 the constants are represented in decimal.
364 '+', "*" and "=" represents the obvious postfix operators.
365 '<' represents a left shift.
369 Parameter Relocation Bits:
373 Previous Relocations: The index field represents which in the queue
374 of 4 previous fixups should be re-applied.
376 Literal Constants: These are generally used to represent addend
377 parts of relocations when these constants are not stored in the
378 fields of the instructions themselves. For example the instruction
379 addil foo-$global$-0x1234 would use an override for "0x1234" rather
380 than storing it into the addil itself. */
